Specification of Letters Patent. Pat t Jan. 31, 192

Application filed November 1, 1918. Serial No. 260,646.

To all whom it may concern:

Be it known that l, Jonson L. McKnLLAR, a citizen of the United States,and a resident of" Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in BcdspringFabrics, of which the following is a specification. V Y I The inventionpertains to metal spring fabrics for use on bedsteads for supporting theusual hair or other soft mattress, and it consists in the novel featuresand structure hereinafter described, and particularly pointed out in theclaims.

The spring of my invention comprises a main carrying frame of usual orany suitable type and a fabric composed of inter engaging links ofspecial outline connected by coiled springs with the end bars of saidframe, the structure as a whole being complete in itself and adapted tobe handled as a unit and applied to or removed from the customarybedstead. One of the purposes of my invention is to provide a fabricwhose links may be readily constructed and assembled and have anefficient yielding action due to their parv ticular shape; and anotherobject of the invention is to provide a spring fabric which will bedurable and the links of which will maintain their shape under strain.Each link is approximately of U-shape having loops at the ends of itstransverse bar, hooks at the free ends of its sides and loops in saidsides adjacent to said hooks.

Theinvention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which:

Fig. 1 is a top View, partly broken away, of spring constructed inaccordance with and embodying the invention;

Fig. 2 is a top view, on a larger scale, of'

bars 10, 1'1 and side bars 12 connecting said end bars, in a manner wellunderstood in this art.

, The fabric of my inventionis composed of a connected series oftransverse and 1011- gitudinal rows of links formed of wire, two ofwhich linksare separately illustrated in 2. The links are numbered 1 1,and all of the links are of corresponding formation, each-being ofvapproximately U-shape and comprisincr sides 15 and a connecting member16. The links 1% are each formed from one piece. of wire, and the sides15 have at their free ends hooks 17 which are formed loops 19, theseloops 19 being formed partly out of the metal of the sides .15 andpartly out of the transverse member 16, the bend of the loops beingformed wholly out of the wire of the member .16 which is offsetinwardly, as shown in Fig. 2, to create the loops 19. The, loops 19 areon the same horizontal planeas the transverse member 16 and adjacentportions ofthe sides 15;

and the loops 18 of each link are respectively bowed upwardly anddownwardly in opposite. directions, as represented in Fig. 3, toaccommodate the loops 18 of the adjacent links with which they areengaged.

The links 14in each transverse row thereof are engaged with each otherat the loops 18, the adjacent sides of each two links being passed onewithin the other link and'the loops thereof broughtorhooked together, as

shown in Figs. 1 and 2; and the links 145 in each longitudinal row oflinks, are hooked together by the engagement of the hooks 17 of eachlink with the loops 19 of the next adjacent link. The hooks 17 areoffset inwardlyfrom the general longitudinal plane of the sides 15 ofthe links so that they may be caught into the loops 19 of the adjacentlinks in a longitudinal row thereof and lie flat and without twisting orstraining the sides of the links, this also resulting in the productionof a desirable spring fabric in which all the links in a longitud nal row thereof are freely hinged together 1n serles.

It is an important feature of my spring fabric that the loops 18 areadjacent to the hooks 17 since thereby I omit the formatlon of undulylong spaces between the ad acent side members of interengaged links atthe open ends of the links.

The links 14 in each transverse row thereof are therefore hooked andhinged together at the loops 18, which are adjacent to the hooks 17, andthe links 14 in each longitudinal row thereof are hooked and hingedtogether by-the engagement of the hooks 17 of each link with the loops19 of the next adjacent link, which loops 19 are set inwardly from thegeneral longitudinal plane of the sides of the links and are in linewith the hooks 17. The connection of the links 14 with one another atthe hooks 17 and loops 19 is'inwardly from the general longitudinalplane of. the sides 15 of the links; and the connection of the linkswith one another at the loops or bends 18 is outwardly from the generallongitudinal plane of said sides 15 and adjacent to the connectionsafforded by the engagement of the hooks 17 with the loops 19 oftherespective links, and this special construction and connection of thelinks results in the production of a superior fabric for the purposesfor which it is intended to be used.

The loops 19 of one end row of links 14 are connected to helicals 20 bymeans of suit able wire connections 21,22, as shown at the upper end ofFig. 1, which helicals 20 are secured to the end bar 10 of the generalframe; and the hooks 17 of the other end row of links 14 are suitablyconnected with helicals 23 secured to the other end bar 11, as shown atthe lower end of Fig. 1.

The main features of my invention reside in the fabric formed of thetransverse and longitudinal rows of links 14 of the character andinterlocked together in the manner described, whereby a highlyefficient, durable, and desirable spring fabric for beds is produced. 7

What I claim as my invention and desire to secure by Letters-Patent, is-I 1. In a bed-spring of the character described, a fabric comprisingtransverse and longitudinal rows of links of approximately U-shapeinterengaged with one another in series at their ends and sides, saidlinks having parallel hooks at the free ends of their sides, loops atthe ends of their transverse member, and outwardly and oppositely bowedloops in said sides and adjacent to the free ends thereof and to saidhooks, and said ing parallel hooks at the free ends of its I sides andset inwardly from the general longitudinal plane thereof, outwardlybowed loops in-said sides and which are respec tively bent upwardly anddownwardly in opposite directions and are adjacent to the free ends ofsaid sides and to said hooks, and loops at the ends of its transversemember and which loops are in line with said hooks, and said links beingconnected together by interlocking the side loops of one link with thesideloops of adjacent links and by engaging the said hooks of therespective links with the said loops at the ends of the transversemember of the respective adjacent links.

3. In a bedspring of the character described, a fabric comprisingtransverse and longitudinal rows of links of approximately U-shapeinterengaged with one another in series at their ends and sides and eachhav ing parallel hooks at the free ends of its sides and set inwardlyfrom the general longitudinal plane thereof, outwardly bowed loops insaid sides closely adjacent to said hooks, and a transverse memberconnecting said sides and. which is offset inwardly to form loops at'theends thereof inwardly the general longitudinal plane of said sides, andsaid links being connected together by interlocking the side loops ofone link with the side loops of adjacent links and by engaging the saidhooks of the respective links with the said loops at the endsof thetransverse member of the respective adjacent links.
